I thought I'd revisit this thread, not because I've ever been on the Newcastle diet but because I said how I was going to approach Type 2.
So first off I am severely motivationally challenged (I'm lazy, I could win medals in procrastination) as a result I rarely food prep which means I have to eat whatever is available, which when I'm at work is usually a massive carb overload. Also I smoke (I have read that smoking affects insulin resistance), I drink to excess which suppresses the liver BUT raises anxiety and hence cortisol.
On the plus side, my evening meal is normally low carb, I bought a pull up bar and watched hours of bodyweight workout videos on YouTube. As I said I'm lazy, I exercise sporadically, but I am seeing changes. More definition in chest, shoulder and arms means more muscle using up glucose. I've lost an inch around my navel. I think my body is becoming more responsive to carbs.
So why write this? Because every little helps!
And the six pack? I think there is the faintest sign, of a hope, of a shadow, of a possibility ... when I cough!
